To all tvh oon it may concern: p

Beit known thatI GILBERT L. HUFF, a

citizen of the United states of America re-' stance, as shown in my Patent No. 1,27 6,923

of August 27, 1918.

In the accompanying drawings which illustrate one form of mechanism made in accordance with m invention, Figure 1 is a front elevation t e supporting plate and handle being broken away, Fi 2 is a view similar to Fig. 1 but showing t e front disk broken away. .Fig. 3 is a rear elevation. Fig. 4 is a section on the line 44 of Fig. 2, and Fig. 5 is a view similar to Fig. 2 but showing the parts in a difierent'position.

6 indicates the side wall of the vendin machine'to which the mechanism is attache said side wall 6 forming the supporting plate for the mechanism. 7 is a casting secured to the wall 6 so as to form between the two parts a coin chute 8 into which the coin is adapted to be introduced through an opening 9 in the wall .6. 10 is a disk situated in the plane of the rear wall of the casting 7 and provided with a hub 11 secured by means of a pin '12 to the operating shaft 13 of the vending machine. 14 is a disk loosely mounted on the shaft 13 adj acent to the disk 10 and provided with a hub 15 which is secured by any suitablemeans, such for instance, as a set screw 16 to a sleeve 17 on the hand wheel 18 for operating the machine. Carried by the disk 10 is a spacing block 19 for dividing the space between the disks 10 and 14 into two coin passages 20 and 21, respectively. The coin passage 20 which is normally in line with the coin chute 8 is of such width that when a coin 22 is introduced into the'mechanism it cannot pass through the passage 20 but is retained between the spacing block 19 and a movable detent 23. This detent 23 is carried by a spring 24 fastened to the casting 7 Specification of Letterslatent.

means of a screw 25 The detent 23 env gages with a stop 26 onthe disk lO and normally prevents the forward movement of the operatin shaft. Carried by the disk 14is a pin 2 which is adapted to come in contact with the coin 22 when in the position shown in Fig. 2 so as to force the detent 23 outwardly to releasethe disk 10.

The pin projects through a slot 28in the disk 10 so as to actuate the said disk 10 after releasing the detent 23. The disks 10 and 14 are held in their normal position relative to each other by means of a coil spring 29 secured at one end to the pin 27 and at the other to a pin 30 in the disk 10.

In order to preventthe backward movement of the disk 10, I provide its hub 11 with a ratchet 31 engaged by a spring pawl 32 carried'on the wall 6.

The operation of my mechanism is as follows: When the parts are in their normal the pin 27 will engage with the edge of the coin thus forcing the detent 23 outwardly to release the stop 26 so that when the Pin. comes into contact with the forward end of the slot it will rotate the disk 10. The shape of the spacing block 19 is such as to insure the engagement of the pin with the forward end of the slot before the detent 23 is allowed to return to normal position. When the disk '10 has been rotated through substantially 180, the coin passage 21 is -brou%ht into alinement with the coin chute 8. his passage 21 is of .such width as to allow any remaining coins in the chute to pass through the machine without engaging with the detent 23 as shown in Fig. 5, thus avoiding injury to the mechanism if a coin is inserted in the machine at the wrong time;

As soon as the revolution of the disk 10 is completed the parts are brought into their normal position with the stop 26 again engaging with the detent 23. i 2

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is: i

1. In a coin controlled mechanism, the

- combination with a pair of disks arranged side by side and having a coin passage therebetween, a detent for locking one or said disks, a projection on said locked disk between which and said detent a coin is adapted to lodge, and a projection on the other of said disks for moving the coin to release the detent while said first named disk is stationary.

In a coin controlled mechanism, the combination with a pair of disks arranged side by side and having a coin passage there between, a detent for locking one of said disks, a projection on said locked disks between which and said detent a coin is adapt ed to lodge, and a'projection on the other of said disks for moving the coin to release the detent while said first named disk is stationary, said second named projection also limiting the relative movement between said disks.

passing through said slot, a spacing block carried in said first named member forforming two coin passages between said members, one of said coin passages being or greater width than the other, said pin being adapted to engage with a coin in the narrow passage to release said detent.

In testimony whereof, I have hereunto set my hand and aflixed my'seal.
